我们报告了一种混合成像技术，能够执行测量的空间，时间和光谱发射特性的激光诱导等离子体通过使用一个单一的检测系统。我们应用这种技术来研究激光烧蚀LiNbO3产生的等离子体，并观察到的现象没有看到这样的细节与标准仪器。这些包括极端线加宽到几纳米伴随着自吸收附近的目标表面，和膨胀动力学，不同的物种之间的差异很大。总的来说，这种新技术提供的丰富的定量信息揭示了等离子体膨胀过程中发生的新的光。
We report a hybrid imaging technique capable of performing measurements of the spatial, temporal, and spectral emission characteristics of laser-induced plasmas by use of a single detection system. We apply this technique to study the plasma produced by laser ablation of LiNbO3 and observe phenomena not seen in such detail with standard instruments. These include extreme line broadening up to a few nanometers accompanied by self-absorption near the target surface, and expansion dynamics that differ strongly between the different species. Overall, the wealth of quantitative information provided by this novel technique sheds new light on processes occurring during plasma expansion.
